A new report from Anthropic revealed five cases of “biological misuse” in which suspicious actors sought to use Claude AI to conduct deadly virus research and investigate toxic venom.

The report documents threat actors using Claude to research and develop drone swarms, anti-torpedo weapons systems, and targeting recommendations.

Chinese AI distillation attacks on Anthropic's Claude grew 12-fold to approximately 190 million exchanges between May and July 2026, as seven Chinese labs -- Alibaba, DeepSeek, Moonshot, and four others -- used fraudulent accounts and proxy networks to extract AI capabilities,

Claude was developed by Anthropic, a San Francisco-based company founded in 2021 by former OpenAI employees focusing on AI safety and research. Dario Amodei, the co-founder and CEO of Anthropic, had served as vice president of research at OpenAI. His sister Daniela Amodei serves as Anthropic’s president.

A developer emailed Claude Code creator Boris Cherny that AI coding had created "friction." Cherny posted his full response.

Anthropic says researchers used Claude for biological work that could support weapons development, exposing new challenges for AI safeguards.
